CAR-VENTILATOR.

SPECIFICATION forming part of Letters Patent No; 766,992, dated August 9, 1904.

Application filed October 12, 1903. Serial No. 176,588. (No model.)

To all whom, it may concern:

Be it known that I, ALEXANDER W. FINLAY SON, a citizen of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Car-Ventilators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to car -ventilators more expressly designed for use in connection with the windows of railway-cars; and. it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.

The object of the invention is to provide simple and eflicient means for introducing into the car a current of air which will serve to ventilate the car and at the same time exclude cinders and dirt, the arrangement being such as to enable the introduction of fresh air to the occupants of the seats when the windows are closed and at the same time to provide for the opening of the windows when desired.

The above object is attained by the arrangement illustrated in the accompanying drawings, in which Figure 1 is an elevation of a portion of a car, showing the application of my invention to the window thereof. Fig. 2 is a fragmentary view, also in elevation, looking from the interior of the car, showing the position of parts with the window raised. Fig. 3 is a fragmentary view in perspective, showing the relative position of parts with the window closed. Fig. 4 is a horizontal section through the apparatus shown in Fig. 3.

transverse section as on line 5 5 of Fig. 3. Fig. 6 is a fragmentary view in perspective of a portion of the rail of the window-sash and a part of the frame which holds the screen.

Referring to the characters of reference, 1 designates the air-intake tubes, which extend in opposite directions and are provided with Fig. '5 is a flaring ends 2. These tubes are joined at their inner ends, and theair-passage therethrough is partially divided by the curved Wall 3,which extends inwardly opposite the opening in the wall of said tubes in which is placed the screen 4. The margin of the opening in which the screen is placed is provided with a turned flange 5, which embraces the edges of said screen. Projecting from the lower edge of said screened opening is a flange 6, through which screws 71nay be passed for the purpose of attaching the device to the sill 8 of the Window, as clearly shown in Fig. 5.

To facilitate the construction of the device, the air-intake tubes are preferably made in two parts adapted to be placed together to form the complete tubes and united by suitable bolts 9 passing through the registering ears 10 of said parts.

The rectangular frame 5, in which the screen 4 is secured, is adapted to lie contiguous to the outer face of the lower rail 11 of the windowsash when the window is down. Formed through said rail is an openinglQ, which reg isters with the opening in the joined air-tubes filled by the screen A. Mounted upon the inher face of the rail 11 of the sash and adapted to move in suitable guides 13 are the sliding doors 14-, which may be made to close the opening 12 through the rail of the sash and by means of which the quantity of air which is admitted through said opening may be regulated.

Attached to the outer face of the rail of the sash, around the opening 12 therethrough, is a metal weather-strip 15, which is trilateral in shape, comprising vertical side portions and a horizontal top portion and having a projecting flange 16, which is adapted to engage the top and sides of the rectangular frame 5,whicl1 embraces the screen at to prevent the entrance of water between said frame and the rail of the sash when the sash is down, as shown in Figs. 3 and 5. The manner in which this weather-strip engages said frame renders it possible for the sash to be raised or lowered at will.

With the apparatus properly in position, as

shown, it will be evident that the movement of the car in either direction will cause a strong current of air to enter one of the tubes, which upon encountering the curved partition 3 will be deflected through the screen 4 and through the opening 12 in the rail of the window-sash into the car, the quantity of air which is permitted to enter being regulated by the sliding doors 14. In this manner each occupant of a seat in the car may have the quantity of fresh air desired Without the accompanying dust and cinders incident to an open window, the arrangement being such as to enable the window to be raised, if desired, without in any sense disarranging the ventilator, which is at once rendered capable of operation upon the closing of the window. It will be noted that when the window-sash is lowered the weatherstrip 15 will engage and slide over the frame 5 around the screened opening and will slide upwardly from said frame when the sash is raised, leaving the ventilating-tubes and the screened educt-opening leading therefrom always in position upon the sill of the window.

The inwardly-extending partition 3, which deflects the air-current against the screen 4, terminates such distance from the screen as to allow a free passage by the end thereof, so as to obviate the possible accumulation of cinders against said partition, as there will be a sufi icient current of air passing said partition to carry the cinders out the rearwardlyextending tube.

' Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a car-window ventilator, the combination of the air-intake tube, a screened opening, a deflector for directing the air through said screened opening, a rail having an opening therethrough which registers with said screened opening, and means for regulating the opening in said rail.

2. In a car-window ventilator, the combination with the air-intake tube, having the oppositely-extending ends and a deflecting-partition at the longitudinal center, the wall of said tube having a screened opening therethrough, the rail of the window-sash contiguous to said screened opening, said rail having a corresponding opening therein, and means for regulating the opening in said rail.

8. In a car-window ventilator, the combination with the air-intake tube, having the oppositely-projecting ends and a deflecting-partition at the longitudinal center, the wall of said tube having an opening therethrough opposite said partition, a screen filling said opening, a window-sash having in the lower rail thereof an opening which registers with said screened opening, and a weather-strip upon said rail around said opening adapted to engage the margin of the screened opening in the air-tube when the window is closed.

4:. In a car-window ventilator, the combination with the air-intake tube having the oppositely-extending ends, and an opening in the side thereof covered by a screen, means for directing the air which enters the tube through said screened opening, a window-sash having an opening through the lower rail thereof in alinement with said screened opening, means carried by the sash for engaging the margin of said screened opening when the sash is down to exclude water therefrom, said engaging means enabling the vertical movement of the sash.

5. In a car-window ventilator, the combination with the air-intake tube having an aireduct opening, said tube being adapted to be mounted on the sill of the window, of a window-sash having in the lower rail thereof, an opening to register when the sash is down, with the educt-opening of the air-tube, means carried by the sash for engaging the margin of the tube around said educt-opening to make a tight closure, said engaging means allowing of a vertical movement of the sash.

In testimony whereof I sign this specification in the presence of two witnesses.

ALEXANDER WV. FINLAYSON.
